This will depend upon RIP resolution. For instance, there are workflows 
where dual resolution is used in order to reduce considerably the amount 
of data on the network and RIPing time. Thus, vector can be RIPed at 
2400 dpi and images will remain at 300 dpi. This will be fine in all 
cases where images are really images and not meant to be treated or used 
as vector replacements. In this case, no matter if the input file was 
even at 800 dpi, it will be RIPed at 300 and the loss will be obvious 
for just about any eyes.

My recommandation is, as much as possible, use the appropriate format 
for any given task. Keep vector for vectors and bitmap for true images. 
That way, you avoid surprises downstream. It’s all about control, in fact.

p.s. Please avoid top-posting as it becomes very difficult to follow a 
thread. I have trimmed down the thread a bit and replaced the order of 
the discussion so the other readers can follow. I have copied to the 
list since I believe this discussion can help others. I very rarely 
answer personnaly to people asking questions to the list. Cheers!
